The term has become meaningless. The same idiots running around in Guy Fawkes masks are also calling themselves Tea Partiers now. The unofficial "fiscal issues only" charter of the Tea Party allowed the movement to be co-opted by #OWS sympathizers and anti-banksters (both groups are virulently anti-Semitic and dominated by Paulestinians).
Rand Paul's election was the beginning of the end of the movement, IMO. Once Rand became the face of the Tea Party, his old man became a sort of defacto father of it.
All good points.
